O 2 ‾ levels in aging skeletal muscle, by histological DHE examination, values represent the area of fluorescence, above a specified threshold, expressed as a percentage of the total area of the muscle cross-section . The values represent the mean ± SEM. Statistically significant differences (P < 0.05) between groups are indicated by lower case letters, where a = 6 m/o, b = 12 m/o, c = 18 m/o and d = 24 m/o.
